FOLDING CABIru-:T-el-:DsTtaADl SPECIFICATION forming part of Letters Patent No. 256,449, dated April 11, 1882.

Application tiled December 22, 1881. (No model.)

To all whom it may concern:

Be itknown that I, FREDERICK STEINBREN- NER, of the city of Buffalo, in the county of Erie and State of New York, have invented a new and usefullmprovementin Folding Beds, of which the following is a specification.

This invention relates more particularly to that cla-ss of folding beds in which the bedframe upon which the mattresses are placed is pivotedv to a vertical stationary frame or case in such manner that when the bed is notrequired for usel the bed-frame containing the mattresses can be swung upward on its pivots to a vertical position, in which it rests against the front ot' the stationary frame, and can be lowered or swung down into a horizontal position when required for use,rand in which the weight ot' the bed-frame containing the mattresses is counterbalanced to a greater or less extent by springs attached to the stationary frame and connected with the rear or shorter rear elevation thereof.

end of the pivoted bed-frameby ropes or ch ains running over suitable guide pulleys. The springs employed for this purpose in folding beds are generally spiral springs, and are very liable to get out of order or break, thereby causing great inconvenience and sometimes personal injury to the persons using such beds. The object ot' my invention is to provide a more substantial and reliable counterbalancing contrivanoe for these folding beds; and it consists of an elliptic spring connected with the stationary frame and the pivoted bed-frame, as hereinafter fully set forth.

In theaccompanying' drawings, Figure l is a fragmentary vertical section ot a folding bed provided with my improvements. Fig. 2 is a Fig. 3 is a fragmentary elevation; and Fig. 4, a horizontal section, illustrating a modified arrangement ot' my iniproved counterbalancing eontrivance.

Like letters of ret'erence refer to like parts in the several figures. Y

A represents the upright stationary frame or case of the folding bed, provided with a head-board, A', and B the rear portion of the Dedframe, provided near its inner or rear end with pivots b, secured to the sides and entering sockets in the stationary case A.

C represents the base-piece of the stationary the middle of its lower part upon a horizontal cross-piece, E, secured to said frame. The spring D is secured to the cross-piece E by clipsy e or other suitable means.

F represents a horizontal cross-piece, which is secured to the upper side of the spring D by clips for otherwise, and g g represent two ropes, preferably constructed of wire, and attached to the ends of the cross-piece F. These ropes extend from the cross-piece F downward, pass loosely through openings h in the lower cross-piece, E, and run around guide-pulleysi k, attached to the lower portion of the main frame A, and connect with eye-pieces l, secured to both sides of the bed-frame A at the inner or 4rear end thereof, the eyes being located at the lower inner corners of the bedframe.

The ends of the crosspiece E are provided with angular teeth m, which engage in the spaces between teeth n, formed in vertical plates N, which. latter are secured to the posts of the ymain frame A, and whereby the cross-piece E is firmly secured to the frame A and at the same time rendered vertically adjustable. By raising and lowering the eross-pieceE the position of the spring D in the main frame and its tension are adjusted as may be required.

It is obvious that an y other equivalentmeans for adj usting the cross-piece E may be adopted. O represents vertical guide-bars,whieh are secured with their upper ends to a stationary cross-piece, P, attached to the fram eA and with their lower ends tothe adjustable crosspiece E. The lower ends of the guide-bars O are provided with vertical slots, through which pass the fastening-bolts q, whereby the guidebars O'are secured to the cross-piece E. This permits the fastening-bolts q to be raised and lowered with the adjustable cross-piece E. The guide-bars O hea-r againstthe outer surfaces of 1 the upper cross-piece, F, and the spring D, and

the head-board A bears against the inner sides of said parts, whereby said parts are prevented from twisting or changing their position in a horizontal plane. The ropes g, passing through the openings h in the lower cross-piece, E, also assist in retaining the upper cross-bar, F, and the spring D parallel with the lower cross-bar, E. As the pivoted bed-frame Bis swung down from a vertical into a horizontal position the ropes g are drawn in the direction ot` the arrows, whereby the upper cross piece, F, is drawn downward and the spring D compressed. The overhanging weight of the bed-frame is to a certain extent balanced by the compression ofthe spring, and when the bed-frame is raised the reaction of the compressed spring assists in returning the bed-frame to a vertical position. The elliptic springD is very strong and durable, and renders the movements of the bed-frame easy and noiselcss.

If desired, the spring D may he arranged in the base of the stationary frame in a horizontal plane, as illustrated in Figs. 3 and 4; but I prefer the arrangement shown in Figs. l and 2, because the parts are more accessible when so arranged.

I claim as my invention- 1. The combination, with the case 0r frame A and the bed-frame B, pivoted thereto, of a spring, D, au adjustable cross-piece, E, to which the spring is secured, and means, substantially as described, whereby the spring is connected with the bed-frame, substantially as set forth.

2. The combination, with the case or frame A and the bed-frame B, pivoted thereto, of a spring, D, a cross-piece, E, supporting the spring, and having teeth m at its ends, and serrated plates N, secured to the frame A,

` whereby the cross-piece E can be adjusted, substantially as set forth.

3. The combination, with the frame A, provided with a head-board, A', and pivoted bedframe B, ot'a spring, D,erosspieces E, F, and P, and guide-bars O, whereby the spring and the cross-piece attached thereto are maintained in their proper position, substantially as set forth.

4. The combination, with the frame A, provided with aheadboard, A', and pivoted bedframe B, ofthe spring D, provided with crosspiece, F, adjustable cross-piece E, cross-piece P, and slotted guide-bars 0, substantially as set forth.
